Not in a cleanroom. I have opened up RD53s and
got them working again.
Hoping (perhaps optimistically) to do the same with this RD54.
If you do, and there are any valuable bits on it, copy them off I've seen people do that and have head crashes
very soon afterward. Given
how low the flying height of the heads is, it would be amazing to NOT have
a head crash at some point thereafter. IIRC, the flying height was about
five
microns back in those days, which was less than the
size of a lot of the
particulate matter in normal room air.
(In recent drives it can be less than 5 nm.)
It is a non-working drive (which is why I want to open it), so I don't have
much to lose really. Thanks for the advice nonetheless.
